Vaeschanan - Cities of Refuge

Why was Moshe insistent on setting aside the cities of refuge on the Eastern side of the Jordan river if they would not be activated until a number of years later? When was Moshe the beneficiary of a 'city of refuge,' or more accurately, a miraculous salvation from Hashem, after which he ran away from Pharaoh? What was the miraculous way he was saved? How did Hashem remind him of this salvation many years later when he was to be sent to save the Jewish people? What is the idea of Moshe 'singing a shira-song' for this salvation? Where is the place of refuge in our times? Find out in this week's Parsha Podcast.
